Mayor Bill de Blasio launched a probe Monday of the city taxi market following a damning report that claimed industry leaders duped drivers with predatory loans and artificially inflated the costs of cab medallions for years– leading to their eventual collapse.

“Today I ordered a joint investigation by the Taxi and Limousine Commission, Department of Finance and Department of Consumer Affairs into predatory practices by brokers in the taxi industry,” the mayor said in a statement.

The 45-day review will identify and penalize brokers who have taken advantage of buyers and misled city authorities, the mayor said.
